Abstract

A system and method for reducing the probability of detection of a Line of Sight (14) type communication and sensor mast (1), the mast (1) having an upper portion (2) extending upwardly relatively the ground (6), and a lower portion (4) closer to the ground (6) than the upper portion (2), where the mast at the upper portion (2) is equipped with at least a communication or sensor element (12), wherein the mast (1) is equipped with an actuator (8) that, based on calculated instructions, is designed to alter the elevation above ground (10) of the mast upper portion (2).
